You're probably referring to depth of field. It's an available lens effect in Babylon.js and will be also added in the next update.
Can I call what effects for a js function?
I'm sorry I'm not certain what you mean. Did you want to add depth of field yourself via direct javascript?
Yeah, but can I call any babylon.js function for a browser excuse js in c2?
Well sure you could do stuff with the "Execute javascript" action of the browser object.
Referring simply to "BABYLON" works. You can access the scene when you use "b3dScene".
Beware though such manipulations require good knowledge of the subject matter.
